Abstract: Abstract of the Disclosure Concentrated   solutions   of   inorganic hydroxylammonium salts can safely be produced in a process for concentrating a dilute solution of an inorganic  hydroxylammonium  salt  in  a  solvent  by contact with a membrane having a sorption side and a desorption side. The process comprises contacting the dilute solution with the sorption side of a membrane, which is substantially permeable to the solvent and substantially impermeable to the solute of the solu-tion,  to sorb the solvent and permit the solvent to flow through the membrane to the desorption side, and desorbing the solvent from the desorption side of the membrane.  Highly concentrated aqueous solutions of hydroxylammonium salts which are heat sensitive are produced by the novel process of the invention which does not require directly heating the solution and is substantially free of hazards.

Abstract: The invention relates to a synchronization method for radio transmitters of a local, e.g. nationwide paging network. A paging network is connected to a public switched telephone network and comprises a paging network unit (PNU), transmitter group controllers (TGC) and transmitter site interfaces (TSI). All controllers are provided with means for receiving, processing and transmitting messages in digital form. Base stations are provided with radio transceivers (Tx, Rx) transmitting radio signals intended for paging or for synchronization of the base stations covering a common overlap area. With the method of the invention, synchronization is performed on the basis of a synchronization plan composed by paging network unit (PNU) and synchronization commands based on the plan. Synchronization proceeds sequentially in a certain order so that each base station (except for the initiator) first receives and then transmits a synchronization signal. Prior to the transmission of a synchronization signal, compensation of delays is executed based on one hand on receiving own transmission and, on the other hand, on information given by the paging network unit PNU about distances between base stations. The synchronous transmission of paging information is confirmed to be independent of a digital data transmission network by determining the exact time of radio transmission of each page according to a plan made beforehand by the paging network unit.

Abstract: 1,250,068. Laying pipes underwater. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 25 Aug., 1969 [26 Aug., 1968], No. 42144/69. Heading F2P. In laying a pipe-line along a preselected route on the floor of a body of water from a pipe-laying vessel having a laterally rigid or a hinged segmented laterally flexible pipe support structure extending outboard of the vessel for directing the pipe-line into the water, the loads imposed on the pipe support structure are sensed, the vessel heading is turned in dependence of the load sensed to reduce the loads on the pipe support and the vessel is moved along the preselected route while maintaining the vessel heading in the turned attitude. The adjustments in vessel heading may be carried out automatically. The load sensed may be the sideways force on the pipe support near its outer end and/or the bending moment at the inner or outer end of the pipe support. The vessel heading may be turned sufficiently to substantially eliminate the stress in the pipe or to reverse the bending moment in the pipe-line at the tip of the pipe support. The loads may be caused by transverse water currents or by misalignment of the vessel and the pipe support with the pipe-line already laid. In a preferred method the difference between the measured force and a desired force is used to generate a heading error signal proportional thereto, the difference between the tension in the pipe and a desired tension generates a tension error signal, the deviation of the vessel from the desired route generates a route error signal and these signals are combined and applied to vessel positioning means in such a manner to turn and/or move the vessel so as to restore the various values to the desired values and hence the error signals to zero and at the same time the timing and the rate of vessel move-up along the route is controlled by controlling the timing and rate at which the pipe is allowed to be payed out or reeled in. The vessel positioning means may consist of a number of rotatable thrust units suitably arranged either with or without conventional propulsion units or a plurality of anchors arranged around the vessel with controllable winches.

Inventor: KOCH BYRON W
IPC: B22D17/22
Filed: 1990-01-22
Granted: 1995-08-15
Abstract: The new locating pins of this invention have notched ends, each of which simultaneously restricts the movement of an expendable core in two orthogonal directions in a die casting die. A plurality of these new pins alone and with other pins project into the space between the printout cavity in a die casting die and the printout portion of an expendable core positioned in that cavity. Other pins having flat ends locate the core in only one directional line. Still other pins having tapered ends require special pockets in the printout section of the core, which pockets have sides that must be formed adjacent to the tapered surfaces of these pins. The configurations of the space around the printout portions of the cores permit molten metal injected into the die to produce a skin or skull over said printout portions, which skin can have thicker ribs or portions through it for further reinforcing the printout portions. These printout portions on the parting line between two dies may have restrictions at the junction of the printout portion with the main portion of the core to form break-off rings. These rings and ribs may be formed either in the die or in the printout portion of the core, or both.

Title: Method and apparatus for catheter exchange by guide wire captivation
Inventor: KEITH PETER T
IPC: A61M25/01
Filed: 1990-08-27
Granted: 2001-11-06
Abstract: An apparatus for exchanging over-the-wire balloon catheters engages a guide wire within a guide catheter. In one embodiment the engagement is by an inflatable balloon in the guide catheter.      Alternatively, the engagement is accomplished by. a captivation wire in the guide catheter that has a collapsible loop portion through which the guide wire extends. Inflation of the balloon or closing the loop portion of the captivation wire within the guide catheter traps the guide wire and restricts its movement relative to the guide catheter. Once the guide wire position is fixed, withdrawal of a first balloon catheter and subsequent introduction of a second balloon catheter over the guide wire is possible without moving the guide wire longitudinally.      Thus, the positioning of the guide wire over a stenosis to be dilated is not disturbed.
